India is preparing to build its first-ever offshore (sea-based) international airport, marking a historic leap in the country's aviation infrastructure. The ambitious project is planned off the coast of Palghar district in Maharashtra, near the upcoming Vadhavan Port, and is expected to become one of the world's largest reclaimed-land airports.
Estimated to cost around ₹76,220 crore, the airport will be constructed on artificial islands and reclaimed land in the Arabian Sea, similar to globally renowned airports such as Kansai International Airport (Japan) and Hong Kong International Airport.
If completed as planned, it will become the third major airport serving the Mumbai Metropolitan Region (MMR) after Chhatrapati Shivaji Maharaj International Airport and Navi Mumbai International Airport.
India's First Airport Built in the Sea
Unlike conventional airports built on land, this mega project will be developed on engineered reclaimed platforms offshore, reducing the need for acquiring large stretches of populated land.
The offshore design aims to:
Minimize land acquisition challenges
Support future aviation expansion
Integrate with India's largest upcoming maritime logistics hub
Strengthen Mumbai's position as a global transport gateway
Location
The proposed airport will be located:
Off the Palghar coast, Maharashtra
Adjacent to the upcoming Vadhavan Port
North of Mumbai Metropolitan Region
Its strategic location allows seamless integration between aviation, shipping, logistics, tourism, and industrial corridors.
Project Cost
The proposed investment is approximately:
₹76,220 Crore
The airport is expected to become one of India's most expensive aviation infrastructure projects.
Planned Passenger Capacity
Once fully operational, the offshore airport is expected to handle:
Passenger Traffic
90 million passengers annually
Cargo Capacity
3 million metric tonnes annually
This would make it one of India's largest aviation and cargo hubs.
Excellent Multi-Modal Connectivity
One of the biggest strengths of the project is its planned transport integration.
The airport will connect with:
Uttan–Virar Sea Link
Providing fast road connectivity to Mumbai.
Delhi–Mumbai Expressway
Offering direct access from western and northern India.
Mumbai–Ahmedabad High-Speed Rail (Bullet Train)
Passengers could reach the airport rapidly using India's first bullet train corridor.
Vadhavan Port
Creating an integrated aviation-maritime logistics ecosystem.
Inspired by World-Class Offshore Airports
India is adopting engineering concepts successfully implemented in:
Kansai International Airport (Japan)
Hong Kong International Airport
Chubu Centrair International Airport (Japan)
These airports demonstrate how reclaimed-land aviation infrastructure can operate efficiently while supporting large passenger volumes.
Current Project Status (2026 Update)
As of mid-2026:
Initial approvals have been received from Maharashtra authorities.
Preliminary feasibility studies are progressing.
Environmental assessments and investment planning continue.
Detailed engineering and financial evaluations are underway before construction begins.
The airport remains in the planning and approval stage, with further clearances required before full-scale development.
Why This Airport Matters for Indian Tourism
The offshore airport is expected to transform tourism in western India by improving access to destinations across Maharashtra and beyond.
Faster Access to Tourist Destinations
Visitors will enjoy improved connectivity to:
Mumbai
Alibaug
Palghar
Dahanu
Nashik
Lonavala
Igatpuri
Shirdi
Gujarat coastal tourism
International Tourism Growth
The airport will strengthen direct international connectivity from Europe, the Middle East, Southeast Asia, and North America.
Cruise Tourism Boost
Its proximity to Vadhavan Port could support integrated cruise-and-air travel packages, enhancing India's maritime tourism sector.
A Major Cargo & Logistics Hub
Beyond passenger travel, the airport is designed to become a powerful cargo gateway.
Expected benefits include:
Faster export-import operations
Improved air freight capacity
Enhanced supply chains
Support for e-commerce logistics
Better connectivity for pharmaceutical and high-value cargo
Sustainability Focus
Modern offshore airports incorporate advanced environmental measures such as:
Coastal protection systems
Flood resilience engineering
Energy-efficient terminal designs
Renewable energy integration
Sustainable water management
Detailed environmental safeguards for India's project will be finalized during the planning process.

Because it will be constructed on reclaimed land and artificial platforms in the sea, rather than on natural land.
How many passengers will it handle?
The airport is planned to accommodate 90 million passengers annually.
How will travelers reach the airport?
It will be connected through the Uttan–Virar Sea Link, Delhi–Mumbai Expressway, and the Mumbai–Ahmedabad Bullet Train.
Is construction underway?
The project has received initial approvals and is currently progressing through feasibility studies, environmental assessments, and investment planning.
Conclusion
India's proposed offshore airport near Palghar represents a bold step toward the future of aviation infrastructure. With an estimated investment of ₹76,220 crore, world-class reclaimed-land engineering, and seamless integration with highways, high-speed rail, and the upcoming Vadhavan Port, the project has the potential to reshape air travel, tourism, and logistics in western India. While it is still in the planning phase, its successful execution could place India among a select group of nations operating large-scale offshore airports and significantly strengthen Mumbai's role as a global aviation gateway.
